Please correct me if I am wrong but have we not gone from a simple do it yourself pH sap test to something complex, where samples are sent to a lab? That's fine but my questions concerning the lab protocal have gone nowhere, leading me to believe that there is no appropriate protocal (beyond standard tissue analysis?). My questions were not responded to.
Can't edit for some reason, but here is the website and company name.

I've already viewed this. I cannot find the lab prococol
e.g.
Mehlich 1, 2 or 3
Morgan or Modified Morgan
SPE
GC-MS
UPLC-MS
HPLC-MS
ESI-MS
ICP
etc.
Most legitimate labs will outline the method(s) used for extraction and analysis. Also is that the lab which does the analysis or do they send it to:
NovaCropControl
Magazijnweg
17-*‐02
5071
NW
Udenhout Netherlands?
The sampling method seems counter intuitive to me, as I deal with live samples daily and see how quickly fungi and bacteria can grow.
They ask for the leaves to be placed in sealed a plastic bag. They even suggest that several leaves can be placed in the same bag. Even overnight, it is a given that mold (fungi) will grow. If the sample is subsequently shipped to Netherlands, this will exacerbate the potential for mold.
The lab I use, when accepting leaf samples, asks for them to be placed into paper bags and shipped overnight. Analysis is done immediately, thus my previous question as to what is the difference? I'm obvoiusly missing something.
I can measure for myself with cardy meters the two main cations, ca and k. Get those right and I figure they are the 20% that matters.
